K99 / R00
What is the NIH K99/R00 grant?
The K99/R00 — Pathway to Independence Award — is a two-phase grant designed to bridge the postdoc-to-faculty transition. The K99 phase (1–2 years) provides mentored research support while you are still a postdoc, and the R00 phase (up to 3 years) activates only after you accept a tenure-track or equivalent independent position. The R00 is portable: you bring it with you to your new institution.

Molecular mechanisms of transcriptional regulation of phototransduction genes in mammalian rod photoreceptors
5R00EY030918-04Elsa Corso-Diaz · STANFORD UNIVERSITY, CA · $249,000 · awarded Aug 18, 2026 · NIHTranscriptional elongation and mRNA processing occur simultaneously and are highly coupled to increase the efficiency and accuracy of mRNA maturation. Splicing is a step of mRNA processing where intronic regions are removed by spliceosome complexes that bind pre-mRNA. Most human genes with multiple exons are alternatively spliced generating numerous…

Specifically, her aim is to develop fNIRS neuroimaging methods that will…
Structural consequences of PKC-dependent phosphorylation of Kv7.2
5R00GM146028-05Crystal Archer · UNIVERSITY OF ARKANSAS AT FAYETTEVILLE, AR · $249,000 · awarded Aug 14, 2026 · NIHProject Summary M channels are critical for regulating the excitability of neurons. Dysfunction of M channel activity can cause epilepsy. While M channels have been intensely studied, the interplay of several G-protein-regulated signaling cofactors on these channels is still poorly understood. M channels are hetero-tetrameric pore structures formed by the…
Social Mechanisms Underlying Sex Differences in Alzheimer’s Disease.

Decision guide
Choose K99/R00 when
Choose K99/R00 if you're 2–4 years into your postdoc, have first-author publications, and plan to apply for tenure-track positions in the next 1–3 years. The K99 is essentially the strongest possible bridge to a faculty offer — many institutions actively recruit K99-funded postdocs.
Choose another mechanism when
If you've passed the eligibility window (>4 years post-PhD typically), you'll need to consider K01 or other career development awards.
Who applies for K99/R00
Postdoctoral fellows typically within 4 years of PhD (some FOAs allow up to 5 years; clinical exceptions exist). You apply during your postdoc, ideally in the second or third year. You must have a strong publication record from your PhD and postdoc and a clear independent research direction.

K99/R00 frequently asked questions
What is the K99/R00 eligibility window?
Most K99/R00 FOAs require you to be no more than 4 years past PhD/MD at the time of initial application (some institutes allow 5 years for clinicians). Check the specific FOA for your target institute.
What is the K99 success rate?
K99 success rates have ranged 25–35% in recent years across most institutes — substantially higher than R01. The selectivity is at the field level: getting the postdoc record to apply is the harder gate.
Can the R00 phase activate if I move to industry?
No. The R00 only activates if you accept a tenure-track or equivalent independent academic position. It cannot be used in industry.
How portable is the R00?
The R00 is fully portable — you can transfer it to any eligible US institution that offers you a qualifying independent position. This portability is one of K99's biggest advantages on the faculty job market.
